guards_choose_dirguard(): replace one XXXX with another.

Browse Source 
I had been asking myself, "hey, doesn't the new code need to look at
this "info" parameter? The old code did!"  But it turns out that the
old code hasn't, since 05f7336624.

So instead of "support this!" the comment now says "we can remove
this!"
